Energy Problems during Marathon Training

by Nick

I have been running for around two years now and I am right in the middle of training for my first marathon in about two months time. I run 5 times a week, but have had a couple of problems with energy during some recent training sessions...

For example last week I had to run 6M Intervals on Tuesday, 8M Steady on Wednesday and was heading out for 7M steady on Thursday. About 2 miles in to the 7M I started to feel tired and weak,a bit jelly-legged, hungry and cold.

Not the first time this has happened and all I could do was limp home at a reduced pace. I've examined my diet and fluids and think that I have a pretty good balance - I weigh 165lbs, consume around 1800-2000 calories per day and genuinely drink about 2 litres of water per day.

Any ideas what I am getting wrong or advice to help me with training?

Thanks in advance!

Hi Nick,
Thanks for your marathon training question.

marathon training, running tips

Marathon training is very tough and takes a lot out of you. I am not training for a marathon at the moment.

But I have recently come back from an injury and am building up the mileage. Long run is getting to about 20-22km / 12.5-14mi.

And I just notice that I am getting a little more tired as well.

This also leads to the occassional "unexplained bad run". E.g. one week you do the exact same run as the week before and suddenly you go 1 minute / km slower or you have to stop in between.

In other words, what you are experiencing is quite normal. They refer to that last stretch of marathon training before taper as the "monster month".

Your mileage is as high as it has ever been, the intensity on some of the runs is high as well.

All of this leads to additional tiredness.

When you are training seriously like you are, you want to make sure you get plenty of energy in via good foods.

Eat, drink and sleep well.

Your energy intake may be a little low. When you run a lot, you need to make sure you eat a lot.

Also consider some extra 'pampering' via a massage or so.

Try to keep it going and know that taper is only a little while away!

Best of luck in the upcoming marathon!
